78/86 Chassis Cab dually thing
« on: September 18, 2010, 09:06:54 pm »
This is my "78" chassis cab project, I had a 78 body sittin in my garage all summer and it had too little rust to send to the scrap yard and one day i came across a 86 C30 flatbed with a 350 and turbo 400 trans that i ended up only payin $400 bucks for, the cab was completely shot so this was a perfect platform to start with, basically my plans with the truck are after the body work and interior are done id like to swap a 12v cummins in it, but first things first im at the point of deciding what color to paint it lol

The 78 rolling chassis i started with


The 86 donar truck


Backing it into the garage to tear it apart


I had to take it for a quick spin around the sub


Old cab coming off


78 cab on and painted before dropping it down


First look with the new cab


Test fitting to get a general idea of how it will look


The only thing i have to modifly is i gota add about a 3 inch strip of sheet metal to close the gap between the bed and cab, i guess the chassis cab trucks were a little longer, and im gona have to do a mini tub on the rear wheel wells to fit the duallys, unless i decide to put a small lift on it and go 4wd, but i gota see what my bank account will allow,

any suggestions on what color i should paint it?

Thanks for lookin

     That actually looks really good

#2: There is no such thing as impossible, it just takes longer.

There is no difference between a 1/2T pickup SRW and a 1T cab/chassis DWR, all regular cab long bed pickups have the same dimensions and wheelbase.
If it isn't close enough (and it isn't based on the pics) you have something mounted incorrectly.

The cab and core support are mounted in the factory locations and everything fit fine there, but it is hard to see in the pics (ill have to take a side shot) but to have the center of the wheel well centered with the rear wheels there is about a 3-4 inch gap between the cab and bed

 When I bought my 84 K30 the owner told me had a small box (maybe 4" of the top of my head) made up to fill in the gap between the cab and the utility body.
 He said the truck came from the factory as a single rear wheel cab&chassis and that the utility box was added. I don't know if someone installed the bed on mine too far back or what but the owner told me the easy way out was to install this box to hide the gap.
 I will get some better pics of it today.

Neither the front or rear tires are actually centered on these.  Was the bed actually bolted down in that picture?

Wow I see what you are saying, yea looks like you need that frame shortened up about at the front of the door(underneath), or front of your bed(underneath) It'd move the front wheels backwards and the rear ones forward. That truck could really look nice.

This is what I came up with on 2 of my beaters.
87 K30 131" wheelbase (the charts list it at 131.5)
84 K30 Cab&Chassis 136" wheelbase.
I may be off a 1" or so in my quick measurements but The C&C is definitely longer.
On the C&C there is a 6" gap between the bed and the utility body with a 5.5" toolbox in between them.
I hope this helps and doesn't add to the confusion.

i think its just the angle of the picture but the front wheels are centered in the wheel well, but no i dont have the bed bolted down yet
